Full textAbstract:
The large number of activities along the West Banjir Kanal river has triggered a change in the condition of its sea waters. The condition most affected is turbidity which caused high concentration of Total Suspended Solid (TSS) in estuary waters and interfere with the entry of sunlight into the waters. The purpose of the study is to determine the effect of the of concentration TSS on the concentration chlorophyll a and dissolved inorganic phosphate (DIP) in the waters of West Banjir Kanal estuary. Water sampling was conducted on October 3, 2019. Water quality parameters such as brightness, pH, temperature, DO and salinity were measured in situ. Meanwhile, chlorophyll a, TSS and DIP measurements were analyzed in the laboratory. The results showed that the highest concentration of TSS, chlorophyll a and DIP were in the estuary area and decreased with further distance from the river mouth with concentration were 70.17-151.50 mg/L, 0.03–2.67 µg/L and 0.71–0.98 µM respectively. Based on the results of the Principal Component Analysis (PCA) showed that TSS affected chlorophyll a by 8.7% (r=0.392; p<0.05) and DIP by 54.46% (r=0.931; p<0.01). The low regression between TSS and chlorophyll a was due to the presence of large amounts of inorganic particles in the West Banjir Kanal river, which makes the river waters become turbid. So, the turbidity of the waters caused the release of phosphate in the sediment to water column which was used by phytoplankton for photosynthesis, so the TSS not only contain sediment particles, but also phytoplankton. Banyaknya aktivitas di sepanjang sungai Banjir Kanal Barat Semarang, memicu kondisi perairan lautnya menjadi berubah. Kondisi yang paling terpengaruh adalah kekeruhan yang menyebabkan tingginya konsentrasi Material Padatan Tersuspensi (MPT) di perairan muara dan mengganggu masuknya cahaya matahari ke perairan. Penelitian ini bertujuan untuk mengetahui pengaruh MPT terhadap konsentrasi klorofil-a dan fosfat inorganik terlarut (DIP=Dissolved Inorganic Phosphate) di perairan Muara Banjir Kanal Barat Semarang. Pengambilan sampel air dilakukan pada tanggal 3 Oktober 2019. Parameter kualitas perairan seperti kecerahan, pH, suhu, DO dan salinitas diukur secara in situ. Sedangkan pengukuran klorofil-a, MPT dan DIP dianalisis di laboratorium. Hasil penelitian menunjukkan bahwa konsentrasi MPT, klorofil-a dan DIP tertinggi di daerah muara sungai dan menurun dengan makin jauhnya muara sungai dengan konsentrasi secara berturut-turut sebesar 70,17-151,50 mg/L, 0,03-2,67 µg/L dan 0,71-0,98 µM. Berdasarkan hasil Analisis Komponen Utama (AKU) menunjukkan bahwa MPT mempengaruhi klorofil-a sebesar 8,7% (r = 0,392; P < 0,05) dan fosfat inorganik terlarut sebesar 54,46% (r = 0,931; P < 0,01). Rendahnya hubungan antara MPT dengan klorofil-a ini disebabkan oleh adanya masukan partikel anorganik dalam jumlah besar di badan Sungai Banjir Kanal Barat yang membuat perairan sungai menjadi keruh. Jadi kekeruhan perairan menyebabkan terlepasnya fosfat di sedimen yang dimanfaatkan oleh fitoplankton untuk proses fotosintesa, sehingga yang terkandung dalam MPT selain partikel sedimen juga fitoplankton.

İki ya da daha fazla materyalin bir araya getirilmesi ile oluşan ve çoğu zaman kendilerini oluşturan materyallerden daha faydalı özelliklere sahip olan malzemelere kompozit malzeme denmektedir. Termoplastik esaslı polimer kompozitlerin üretiminde ise lignoselülozik materyaller ile polietilen (PE), polipropilen (PP), polivinil klorür (PVC) gibi plastikler kullanılmaktadır. Lignoselülozik materyaller ve termoplastik esaslı polimerlerin karışımıyla, plastik içerikli ürünlere benzer yöntemlerle üretilen malzemelere Ahşap-polimer kompozitleri (APK) denir. Ahşap polimer kompozit üretiminde çeşitli organik ve inorganik dolgu maddeleri kullanılmaktadır. Kalsiyum karbonat, talk, kalsiyum sülfat, alüminyum silikat ve Titanyum Dioksit gibi inorganik dolgu maddelerinin fiyatının pahalı oluşu ve makine aksamında yapmış olduğu aşınma dolayısıyla araştırmacılar ve endüstri kuruluşları alternatif dolgu materyali arayışına girmiştir. İnorganik dolgu materyaline alternatif olarak düşünülen buğday sapı, odun unu, orman endüstri atıkları ve yıllık bitkiler gibi organik dolgu maddeleri doğada bol olarak bulunmaları ve fiyatının ucuz oluşu dolayısıyla oldukça büyük avantajlar sağlamaktadır. Organik dolgu maddeleri ürünün maliyetini düşürdüğü gibi aynı zamanda ciddi performans artışları da sağlamaktadır. APK üretiminde saf (bakir) plastik kullanılabildiği gibi geri dönüşüm plastiklerde kullanılabilmektedir. Ülkemizdeki mevcut orman endüstrisinin oluşturmuş olduğu atıklar ve tarımsal atıklar ve bunun yanı sıra oluşan ciddi plastik atığı göz önüne alındığında bu tip malzemelerin APK üretiminde değerlendirilmesi potansiyeli görülmektedir. Bu nedenle ülkemizdeki tarımsal ve orman endüstrisi atıkları kullanılarak saf veya geri dönüşüm plastiklerle OPK üretiminde, üretim parametrelerinin ve üretilen malzemelerin özelliklerin belirlenmesi, bu potansiyeli ortaya çıkarmak için zaruri hale gelmiştir. Bu çalışmada atık alüminyum polietilen (Tetrapak) ve atık pirinç saplarından elde edilen unlar kullanılarak ahşap polimer kompozitler üretilmiştir. Ekstrüzyon ve enjeksiyon kalıplama işlemlerine tabi tutularak üretilen kompozitler üzerinde çekme ve eğilme direnci dayanımı testleri gerçekleştirilmiştir. Kompozit bünyesindeki pirinç sapı unu miktarındaki artışın kompozitlerin çekme ve eğilmede elastikiyet modülü değerlerini iyileştirdiği ancak kompozitlerin çekme, eğilme direnci değerlerinde genel olarak bir azalmaya sebep olduğu tespit edilmiştir. Determination of Mechanical Behaviour of Wood Polymer Composites Manufactured Using Waste Aluminium Polyethylene (Tetra Pak) and Brass Handle In this study, we evaluated some mechanical properties of aluminum polyethylene (Tetra Pak) composites reinforced with rice husk flour. To meet this objective, rice husk flour was compounded with aluminum polyethylene with coupling agent (MAPE) in a twin screw co-rotating extruder and then was manufactured by injection molding process. The modulus in the flexural and tensile improved with increasing rice husk flour content while the tensile and flexural strengths of the samples decreased. The use of maleic anhydride polyethylene had a positive effect on the mechanical properties of the aluminum polyethylene composites reinforced with rice husk flour. This work showed that the composites treated with maleated polyethylene could be efficiently used as decking products, due to satisfactory mechanical properties of the composites.

Bu çalışma farklı demir formlarının kadmiyumla kirletilmiş ortamlarda fasulye bitkisinin gelişiminde meydana getirdiği değişimlerin belirlenmesi amacıyla kurulmuştur. Deneme, faktöriyel deneme desenine göre üç tekrarlamalı olarak, Toprak Bilimi ve Bitki Besleme Bölümüne ait iklim odasında, kontrollü koşullarda yürütülmüştür. Farklı demir formlarının (inorganik (FeSO4.7H2O), organik (Fe-EDDHA) ve nano demir) Fe0:0 mg kg-1 ve Fe1: 15 mg Fe kg-1 olmak üzere iki dozu uygulanmış, Cd-nitrat formunda Cd0: 0 mg Cd kg-1, Cd1: 40 mg Cd kg-1 ve Cd2: 80 mg Cd kg-1 olacak şekilde kadmiyum uygulanmıştır. Deneme tohum ekimini izleyen sekiz hafta sonra sonlandırılmıştır. Hasat edilen bitkilerde bitki gelişim kriterleri üzerine kadmiyum ve demir uygulamalarının etkisi belirlenmiştir. Farklı demir formlarının bitki boyu (p<0.05), kök boyu ve kök kuru ağırlığı (p<0.01) üzerine etkileri istatistiksel olarak önemli bulunmuştur.

Irigasi dan instrumentasi merupakan salah satu faktor yang berperan penting dalam perawatan saluran akar gigi. Penggunaan instrumen manual dan instrumen yang digerakkan mesin, akan menghasilkan smear layer yang menutupi dinding saluran akar dan tubuli dentin yang terbuka.Pembersihkan debridement secara menyeluruh serta pembersihan smear layer merupakan landasan untuk mencapai keberhasilan perawatan saluran akar gigi. Irigasi dengan sodium hipoklorit (NaOCl) yang dikombinasi dengan bahan khelasi seperti Ethylenediaminetetraacetic (EDTA) telah direkomendasikan untuk pembersihan komponen organik dan komponen inorganik dari smear layer secara efektif. Namun, EDTA dapat bersifat erosif terhadap dentin, konsekuensinya mempengaruhi sifat kekerasan, permeabilitas dan pelarutan dentin di bagian dalam akar gigi. Penggunaan NaOCl tidak mampu membersihkan smear layer, karena hanya efektif terhadap debris organik. Oleh karena itu,dibutuhkan penelitian untuk mencari larutan irigasi yang lebih kompatibel, efesien membersihkan smear layer dan menyebabkan erosi dentin yang lebih rendah. Saat ini, chitosan telah diteliti di bidang kedokteran gigi.Chitosan adalah polisakarida alamiah, berasal dari deasetilasi chitin yang terdapat pada cangkang kepiting dan udang. Chitosan memiliki kemampuan khelasi, biokompatibel, biodegradasi, bioadhesi dan tidak toksik terhadap tubuh manusia. Hasil-hasil penelitian terbaru telah menyimpulkan bahwa irigasi akhir dengan larutan Chitosan 0,2% setelah irigasi dengan larutan NaOCl, lebih efesien dalam membersihkan smear layer dibanding bahan irigasi lainnya dan menyebabkan erosi lebih sedikit pada dentin akar gigi. Chitosan dapat dipertimbangkan sebagai alternatif bahan irigasi dalam perawatan saluran akar gigi karena memiliki kemampuan khelasi pada dentin saluran akar gigi.

Çevresel problemler göz önüne alındığında, katı atıkların bertarafı birçok dünya ülkesinin temel problemlerinden birisidir. Bu doğrultuda farklı kaynaklarda oluşan ve büyük ölçüde çeşitlilik gösteren katı atıkların bir kısmının tekrar kullanımı hedeflenmektedir. Böylece ekonomik fayda sağlanmaya çalışılmaktadır. Katı atıkların yarattığı çevre kirliliğine, su kaynaklarında meydana gelen ekolojik problemlerin de eklenmesi insanlık için daha büyük risklerin habercisidir. Dolayısıyla katı atıkların bertarafında önemli yeri olan tekrar kullanımın, sadece ekonomik faydası değil, atığın atıkla giderim esasına katkısı da tartışılmaya başlanmıştır. Tüketim hızının giderek arttığı dünyada, özellikle tarımsal kökenli atıkların, su arıtımında adsorbent olarak kullanılmasıyla yüksek arıtma verimleri sağlandığı gözlemlenmiştir. Bu durumu takip eden çeşitli araştırmalar, muz kabuğu, ayçiçeği sapı, pirinç kabuğu, portakal kabuğu gibi tarımsal kökenli atıkların yanı sıra kül ve arıtma çamuru gibi atıkların da organik ve inorganik bir takım kirleticilerin su ortamından arıtılmasında önemli rol oynadıklarını göstermiştir. Böylece adsorbent maliyeti nedeniyle çoğu zaman işletmeler tarafından uygun görülmeyen ve pilot ölçekli çalışma olarak kalan adsorpsiyon prosesinin kullanılabilirliğinin arttırılması şansı doğmuştur. Adsorpsiyon proseslerinin yaygınlaştırılması ile atıksu arıtımında elde edilebilecek yüksek verimlerin yanı sıra bu proseslerde adsorbent olarak kullanılan atıkların bertarafı da sağlanmış olacaktır. Aynı zamanda bu durum atıkların başka proseslerde de benzer şekilde değerlendirilmelerinin önünü açmaktadır. Bu çalışmada özellikle endüstriyel bazda kullanımlarında ekonomik ve çevresel faydalar sağlayacak atık kökenli adsorbentlerin türleri ve kapasiteleri karşılaştırmalı olarak değerlendirilmiştir. Principle Of Removal With Waste Of Waste In Environmental Protection Solid wastes disposal is one of the fundamental environmental problems of many world countries. By this way reusing of some parts of solid wastes which composed in different sources and shown large scale variety have been aimed. So these ways have been aimed to provide economic benefits. Ecological problems of water resources have been added to solid wastes impurity and these facts have shown bigger risks for humanity. So reusing which is more important of solid waste disposal makes a contribution to waste removal with waste except economical benefits. Especially researchers have been observed to agricultural adsorbents efficiency on the adsorption of water treatment. Some of different research shown that inorganic wastes like ash and sewage sludge as important as agricultural wastes like banana peel, sunflower stem, rice husk, orange peel on wastewater treatment. In this way adsorption’s availability is getting higher for process. High treatment efficiency on wastewater treatment and waste disposal will actualize by adsorption. And these will be example for the other process.

ABSTRACTWater treatment plants (WTPs) produces residues in the form of alum sludge during the treatment process. In Indonesia, due to various techno-economic constraints, some WTPs are not equipped by sludge treatment systems, so the generated alum sludge is discharged directly into water bodies without appropriate treatment. This condition may pollute water bodies because alum sludge contains various contaminants such as solid particles, organic compounds, inorganic metals, aluminum, and pathogenic microorganisms. This study aims to evaluate the characteristics of alum sludge from aspects of quality and quantity, which is indispensable for the design of sludge treatment facilities. Citayam WTP (capacity of 120 L/s) in Depok City was chosen as a case study. The study was conducted in several stages as follows: (i) survey and sampling; (ii) quality analysis of alum sludge; (iii) estimation of sludge generation; and (iv) mass and volume balance analysis. Results of comparative analysis of alum sludge quality against the Regulation of Minister of Environment of Indonesia 5/2014 shows alum sludge from flocculation units meets quality standards. In contrast, alum sludge from sedimentation and filter units were exceeded for TSS, COD, and Total Coliform parameters. Quantity-wise, the estimation of sludge generation by theoretical and empirical methods was found to be 1,898 kg/day and 4,854 kg/day. Analysis of mass and volume balance using STAN software indicates that the theoretical approach is quite representative, while the empirical method tends to be over-estimated.Keywords: alum sludge, sludge quality, sludge generation, water treatment plant, case studyABSTRAKInstalasi pengolahan air (IPA) dalam proses pengolahannya akan menghasilkan residu berupa lumpur alum. Di Indonesia, akibat berbagai kendala tekno-ekonomis, masih terdapat IPA yang belum memiliki sistem pengolahan lumpur alum sehingga langsung dibuang ke badan air tanpa pengolahan. Kondisi ini berpotensi mencemari badan air karena lumpur alum mengandung berbagai kontaminan seperti partikel padat, senyawa organik, inorganik, logam aluminium serta mikroorganisme patogen. Penelitian ini bertujuan untuk mengevaluasi karakteristik lumpur alum dari aspek kualitas dan kuantitas yang merupakan informasi penting dalam perancangan sistem pengolahan lumpur. IPA Citayam (Kapasitas 120 L/detik) di Kota Depok dipilih sebagai objek studi. Penelitian dilakukan dalam beberapa tahapan yakni survei dan sampling, analisis kualitas lumpur alum, estimasi timbulan lumpur, dan analisis neraca massa dan volume. Hasil perbandingan analisis kualitas lumpur alum terhadap PermenLH 5/2014 menunjukan lumpur alum dari unit flokulasi memenuhi baku mutu sedangkan lumpur alum dari unit sedimentasi dan filter melebihi baku mutu lingkungan untuk parameter TSS, COD dan Total Koliform. Dari aspek kuantitas, estimasi timbulan lumpur yang dilakukan dengan metode teoritik dan empirik berturut-turut sebesar 1.898 kg/hari dan 4.854 kg/hari. Analisis neraca massa dan volume menggunakan software STAN mengindikasikan bahwa metode teoritik cukup representatif, sedangkan perhitungan dengan metode empirik cenderung menjadi over-estimasi.Kata kunci: lumpur alum, kualitas lumpur, timbulan lumpur, instalasi pengolahan air, studi kasus

Full textAbstract:
Oil sands process water (OSPW) contains organics, inorganics, and particles. To understand and improve the ozonation performance, it is crucial to clarify the effect of inorganics and particles on the ozonation of OSPW organic compounds. In this study, OSPW containing only inorganic fraction (OSPW-IF) was obtained after the organics were adsorbed onto granular activated carbon. A model naphthenic acid (NA) compound, cyclohexanecarboxylic acid (CHA), was dissolved in OSPW-IF (CHA-OSPW-IF) and NaHCO3 buffer (CHA-Buffer). Ozonation of CHA-Buffer achieved higher CHA removal and lower utilized ozone dosages compared to CHA-OSPW-IF. Some inorganic ions present in OSPW (i.e., NH4+, HCO3−, and Cl−) caused a slight reduction of CHA degradation. Inorganics in OSPW inhibited the degradation of natural-occurring NAs while a negligible influence of particles on the ozonation of NAs was found. This research suggests that ozonation could be better utilized as an intermediate or post-treatment step in a treatment train for OSPW reclamation.

Full textAbstract:
When evaluating the composition of black liquor using material balance techniques that estimate the organics from the wood and the inorganics from the cooking liquor, the solids content of the black liquor is determined to be roughly 1/3 inorganic matter and 2/3 organic matter. When actual laboratory testing using simplified ashing methodologies are performed, the results typically suggest that black liquor solids contain roughly 43%-49% organics and 51%-57% inorganics. We determined that the applied hydroxide and sulfide mineralize carbon and oxygen from the organic portion of the black liquor and convert it to carbonate and sulfate during the cooking and ashing process, thus increasing the apparent inorganic content of the black liquor. This becomes problematic when attempting to estimate total black liquor production using the organics removed during cooking and the inorganic content using results from the ashed black liquor sample. We used Microsoft Excel material balances to develop a conversion factor to correct the laboratory test results. Multiplying the percent ash in the laboratory test by 0.65 to 0.70 provided a more realistic estimate of the initial inorganics to be used along with organics removed in the digester to estimate black liquor production. This conversion factor was determined to be independent of pulp yield and white liquor charge in the digester. The initial white liquor composition, as reported by the ABC test, does have a slight effect on this value.

Nature is an exquisite designer of inorganic materials using biomolecules as templates. Diatoms create intricate silica wall structures with fine features using the protein family of silaffins as templates. Marine sponges create silica spicules also using proteins, termed silicateins. In recent years, our group and others have used biomolecules as templates for the deposition of inorganic materials. In contrast with the traditional materials science approach, which requires high heat, extreme pH and non-aqueous solutions, the bio-based approaches allow the reactions to proceed usually at near ambient conditions. Additionally, the biological templates allow for the control of the inorganic nanoparticle morphology. The use of peptides and biomolecules for templating and assembling inorganics will be discussed here.

Karakteristik batubara dari dua wilayah prospek batubara di Sumatera dievaluasi dengan menggunakan metode kimia dan petrografi batubara. Penelitian terfokus pada evaluasi peringkat (tingkat pembatubaraan di daerah penelitian), tipe (komposisi material organik dan lingkungan pengendapan batubara) serta grade (kandungan material inorganik yang bisa berpengaruh terhadap proses utilisasi) batubara. Lapangan X memiliki lapisan batubara yang merupakan bagian dari Formasi Muaraenim dan Kasai Cekungan Sumatera Selatan sedangkan batubara pada lapangan Y merupakan bagian dari Formasi Petani Cekungan Sumatera Tengah. Sebanyak enam conto batubara dari lapangan X dan 8 conto dari lapangan Y digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa kedua lapangan memiliki batubara dengan karakteristik yang berbeda. Walaupun batubara di kedua daerah termasuk dalam kategori lignit, nilai rata-rata reflektansi huminit batubara Lapangan Y sedikit lebih tinggi dari lapangan X. Hal ini mengindikasikan bahwa batubara lapangan Y mengalami pengaruh peningkatan termperatur dan pembebanan yang lebih tinggi dari lapangan X. Berdasarkan hasil analisis komposisi maseral, batubara lapangan X dapat dibedakan ke dalam 3 fasies: fasies 1 (huminit >90%, kandungan inertinit dan liptinit <10%), fasies II (huminit 80% s.d. 90%, inertinite 10% s.d. 15%, dan liptinit 10%) serta fasies III (huminit 75% s.d. 85%, inertinit 15% s.d. 20% dan liptinit <10%). Sementara batubara lapangan Y lebih homogen dan dapat digolongkan ke dalam satu fasies (huminit >90% dan liptinit serta inertinite <10%). Hasil plot Gelification index (GI) dan Tissue preservation index (TPI) menunjukkan bahwa batubara lapangan X diendapkan pada lingkungan limnic-marsh hingga limno telmatic sedangkan batubara lapangan Y pada lingkungan limnic hingga telmatic marsh. Banyaknya konkresi pirit pada batubara lapangan Y mengindikasikan bahwa batubara tersebut mendapat pengaruh laut yang lebih besar daripada batubara lapangan X Batubara di kedua lapangan dapat dianggap sebagai batubara grade tinggi atau batubara bersih karena memiliki kandungan sulfur (<10%) dan abu yang relatif rendah (<10%). Hanya satu conto (SJ2) yang memiliki kadar abu tinggi (>50%) menunjukkan bahwa conto tersebut bukan batubara. Sebagai kesimpulan, perbedaan karakteristik batubara lapangan X dan Y mendukung teori bahwa batubara dengan sejarah pengendapan yang berbeda akan menghasilkan karakteristik yang berbeda.

Ülkelerin sanayileşmesi ile birlikte endüstriyel bazlı su kullanımının artması ve son yıllarda ortaya çıkan küresel ısınma sorunu, yüzeysel ve yeraltı su kaynaklarının tükenmesine sebep olmaktadır. Endüstriyel atıksuların doğaya yaptığı etkiler önemli düzeyde, doğal dengeyi değiştirici ve bazı durumlarda geri dönülmez nitelikte olmaktadır. Endüstrilerden kaynaklanan atıksular, evsel atıksulara göre kaynak, miktar ve karakter açısından büyük farklılıklar gösterirler. Bu nedenle endüstri tesisinin çıkış sularının doğal su ortamlarının kirletmesini engelleyecek şekilde arıtılması gerekmektedir. Bu atıksuların arıtılıp geri kazanılması ile hem su kaynaklarının tüketimi hem de deşarj edilen arıtılmış atıksuların miktarı azaltılmakta ve çevresel etkileri en aza indirilebilmektedir. Ülkemizdeki en büyük endüstri dallarından biri olan tekstil endüstrisi, çok su tüketilen, kullanılan hammadde ve kimyasal maddelerin, gerçekleştirilen işlemlerin, her işlem için uygulanan teknolojilerin çeşitliliği nedeni ile farklılık gösteren ve üretilen ürüne bağlı atık kaynağı olarak son derece değişken yapıya sahip bir endüstridir. Tekstil endüstrisi atıksularının en belirgin özelliği, yüksek miktarda organik ve inorganik kimyasal içermesi ve yüksek toplam organik karbon (TOK), kimyasal oksijen ihtiyacı (KOI) ve yoğun renk içeriğidir. Alıcı su kaynaklarına verilen boyar maddeler organik yük olarak bu kirliliğin küçük bir kısmını oluşturmaktadır; ancak alıcı ortamda çok düşük konsantrasyonlarda boyar madde bulunması bile estetik açıdan istenmeyen bir durumdur. Bu nedenle boyar madde içeren tekstil endüstrisi atıksularından renk giderim prosesleri ekolojik açıdan önem kazanmaktadır. Günümüzde boyar maddelerin giderimi büyük oranda fiziksel ve kimyasal yöntemlerle gerçekleştirilmektedir. Bu çalışmada, atık döküm kumlarının, tekstil endüstrisi atık sularında renk gideriminde adsorbent olarak kullanılması amaçlanmaktadır. Using of Waste Foundry Sands in Removal of Textile Wastewater Nowadays, the accelerating need of water due to usage of water in industralized countries and global warming is causing all water sources to be exhausted. The effects the industrial wastewater made to the nature are important level, changer of natural balance, and sometimes non returned position. By reusing the treated the wastewater, not only the consumption of natural water sources has been prevented, but also the amount of discharged treated wastewater and its effects to the environment has been decreased. The wastewater resulted from industries shows big differences according to the wastewater in houses in the conditions of resource, amount, and character. So output water of the industry establishment has to be purified to prevent not to dirty natural water places. Textile industry is one of the biggest industries of Turkey and it consumes Access amount of water. As there are several methods and technologies used in this sector due to the different raw materials and various chemicals, the wastewaters obtained vary related to the products produced. The most prominent feature of textile industry wastewater is contained high amounts of organic and inorganic chemicals, and high total organic carbon (TOC), chemical oxygen demand (COD) and intense color. The discharge of dyes into the receiving waters constitutes only a small portion of water pollution. However the presence of very low concentrations of dyes in receiving waters is aesthetically undesirable. Therefore, treatment processes removing dyes from textile effluents have become important in order to conserve receiving waters. In this study is to investigate using the adsorpsion method of removal with waste foundry sands, which are used expecially dye nd textile industries and are an important polluting agent in the waste water dumped into the environment by these industries.

Abstract Reverse osmosis concentrate (ROC) from wastewater reclamation plants have high concentrations of organic and inorganic compounds, which have to be removed before its disposal. Forward osmosis (FO) and nanofiltration (NF) membranes were tested to treat the ROC for possible water reuse. This research investigated the combined and individual influence of organic and inorganic matter on the fouling of NF and FO membranes. The results revealed that the NF membrane removed most of the organic compounds and some inorganics. The study further highlighted that the FO membrane at NF mode removed the majority of the inorganic compounds and some organics from the ROC. A pretreatment of granulated activated carbon (GAC) adsorption removed 90% of the organic compounds from ROC. In addition, GAC adsorption and acid pretreatment of ROC improved the net water permeate flux by 17% when an FO membrane was used in the NF system. Acid treatment (by bringing the pH down to 5) helped to remove inorganic ions. Therefore, the resultant permeate can be recycled back to the RO water reclamation plant to improve its efficiency.
